Arizona asks court to reject latest SB 1070 challenge

Lawyers for Arizona Gov. Jan Brewer are asking a federal appeals court to turn back the latest effort by foes to block the most contentious part of the state's tough new immigration law.

Opponents of part of the law requiring police to question some people they contact about their immigration status want the 9th U.S. Circuit Court of Appeals to block its enforcement. That provision survived a U.S. Supreme Court review.

Brewer's lawyers told the appeals court in a filing late Friday that the high court has already spoken on the matter. They say opponents have brought no new arguments that would prevail and make it proper to block enforcement of the law.

The provision went into effect Tuesday after a federal judge in Phoenix said it could be enforced.
